Saint Louis men's basketball coach Rick Majerus will not return to the team because of a serious heart condition.
The 64-year-old Majerus ended the school's 12-year NCAA tournament drought last season with a 26-win team that won its opening game and took top regional seed Michigan State to the wire.
The Billikens were ranked for the first time since the 1994-95 season.
Majerus has been undergoing evaluation and treatment in California for ongoing heart trouble.
He and his representatives have requested that the school's department of athletics not provide additional details regarding his health.
Majerus has a 25-year record of 517-216 with just one losing season and was 95-69 in five seasons at Saint Louis.
He has taken 12 teams to the NCAA tournament and four to the NIT and his 1998 Utah team lost in the NCAA championship game to Kentucky.
Jim Crews, added to the coaching staff last season by Majerus, is the school's interim coach.
